This work is a collaboration <strong>of</strong> Aberystwyth University IBERS,<br />

the National Museum <strong>of</strong> Wales and the National Botanic Garden <strong>of</strong><br />

Wales. There were numerous questions put to Mike after his<br />

presentation. The one that I particularly remember was ‘How do<br />

you sex a bee?’<br />

NOTE Rhos pastures are flower-rich grasslands containing a mixture <strong>of</strong><br />

heathland and purple moor grass vegetation and providing a valuable<br />

habitat for endangered species <strong>of</strong> wildlife such as the marsh fritillary<br />

butterfly. Modern farming practices – including neglect, which allows<br />

the growth <strong>of</strong> scrub – have put this habitat increasingly at risk. The term,<br />

which ecologists now apply in other parts <strong>of</strong> Britain, derives from the<br />

Welsh rhos, meaning ‘heath’, and this is a habitat in which Ceredigion is<br />

well represented.<br />

Mike explained that thanks to this collaboration Wales hopes to be the<br />

first nation to complete the DNA barcoding <strong>of</strong> all <strong>of</strong> our species <strong>of</strong><br />

flowering plants – 1.143 <strong>of</strong> them – and to use this information as a basis<br />

for further investigation into plant behaviour. It is exciting to find that<br />

Ceredigion has played a major part in this research. The three ‘rhos’<br />

pastures monitored in the pollinator study were Glandenys, Fullbrook<br />

and Glyn yr Helyg – the latter two both classified among Ceredigion’s<br />

Sites <strong>of</strong> Special Scientific Interest (SSSIs).<br />

The colourful pie-charts from the study showed considerable seasonal<br />

variation as well as surprisingly different preferences in the tastes <strong>of</strong><br />

male and female bees – various Bombus species, whose similarities can<br />

confuse even the experts. And at this point we gardeners even<br />

encountered some actual plant names, albeit Latin ones: not all <strong>of</strong> us<br />

could remember, for instance, that the bee-favoureded Rhinanthus is<br />

yellow rattle and the Succisa species he mentioned is devil’s bit scabious.<br />

THE MAGIC OF ROSES<br />

LECTURE by GARETH DAVIES on 8 FEBRUARY<br />

All those who attended this talk must feel very much more<br />

confident about the roses in their gardens. Gareth’s obsession with<br />

roses started in the early 1960s, when he joined the Rhondda Rose<br />

<strong>Society</strong>, and the Hybrid Teas have always been his favourites.<br />
